Endpoint Protection

I am managing SEP 14 across 3 sites. In 2 of the sites there is a high security zone behind a DMZ. I have licenses for the 3 sites (3000 seats) and another set for the secure zones, which have a limited number of clients (no more than 200 devices, 800 seats purchased). What would be the best approach in terms of licensing the 2 groups?

Import the license into each of the SEPMs and as long as your client count doesn't go above the total allotment count then it should be good.
